Does any one have knowledge of how many sets of HyperPak exhaust manifolds the factory produced ? |

Mike, I don't know if anyone would know the answer. I know the history of my parts. Bought new in 1961, went on a Lancer and raced from day one. Second owner used them on a Studebaker circle track car in the mid 60's. Second owner sold them to me in 1972. In my experience you will find about 5 to 10 intakes to every set of exhaust manifolds you find. You could buy the items without buying the kit. I have thought about doing a registry of parts just out of interest, but not sure what it would prove. You will never find all them, they are hid away in corners all over the world. I only know about 4 sets, but I don't know much. Maybe owners on SS.Org will respond. |

Thank you for the reply. I have a set and have been exploring reproducing them for a couple of years now. I'm just trying to get a feel for how many the factory may have originally produced. |

What surprises me is no one (I think) has produced a good stainless steel 'shorty' type header for the Slant Six. Something like what Mopar would put on the engine if it were produced today. |

IIRC, there were roughly 200 HPak kits made available for sale. I have an old article on my computer at home, I'll post it when I get home. |

I would really like to see that! I have heard stories about dealers throwing them in the dumpsters after they set on shelves for years. |

So I just did the math, the complete kit was 403.30. I chose 1961 and adjusted for inflation that is $ 3,395.17. It doesn't take much thought to figure not many people would fork out that much cash back in he day. |

  Not sure where I found this posted before, but I found it in an old folder in my Downloads yesterday while cleaning out old memes.

Yes! THe Dont sell the Hyper-pack to anybody Sub section are wise words. My 69 Dart is just that. Idles between 500-1800 RPM - THe hotter it gets the better - below 60°F fuggadabout it. It would have to be driven with 3 feet.  Thanks for posting Dennis! Greg |
